From: Rafał Miłecki <[email protected]> Most of firmwares support creating monitor interface. The newest ones explicitly /announce/ it using a "monitor" entry in the list of capabilities.
Check (and store) internally info about monitor mode support using a new feature flag. Once we sort out all details of handling monitor interface it will be used when reporting available interfaces to the cfg80211.
